How to permanently prevent black mold in humid apartment?« Back to Previous Page

The wall behind your dresser is likely a thermal bridge, where the outside heat meets your cooled interior, creating condensation that feeds mold. In Dubai's climate, this is a common issue in apartments, especially in areas like Marina with high humidity.

First, move the dresser away from the wall immediately to allow air circulation and dry the area thoroughly. Wipe the existing mold with a diluted vinegar solution, but this is only a temporary fix. The long-term solution requires addressing the moisture source.

To prevent recurrence, you must improve ventilation and reduce humidity. Use a dehumidifier in the bedroom, especially during the more humid months. Ensure your AC unit is running efficiently and that its drain lines are not clogged, as this can contribute to indoor humidity. Consider requesting your building's facility management to inspect the external wall insulation; inadequate insulation is often the core problem in these cases.

For a persistent issue like this, a professional inspection is wise. They can use a moisture meter to identify the exact condensation points and an infrared camera to find hidden dampness within the wall. In many cases, the only permanent fix is remedial work on the wall's insulation by the building management to break the thermal bridge.

Since your children are experiencing symptoms, a lab test to identify the mold species can clarify the health risk and provide documented evidence to encourage your building management to take action.
